Choosing the optimum TV screen size should be based on how far you'll be sitting from it, and what you'll be watching, as well as on your own viewing preferences.
In a Nutshell
Sitting up close to your TV gives you a more immersive, theater-like viewing experience. The image fills up more of your field of vision, so your eyes are less likely to stray from the action.
You're sitting too close if you can make out the screen's "structure" — those rows and columns of pixels that look like tiny dots.
The expression "bigger is better" actually makes a pretty reasonable guideline when you're trying to decide on TV screen size.
Go with the largest screen your room, viewing distance, and budget will accommodate.
We occasionally hear people wishing their TV's screen was bigger, but rarely hear them wishing their screen was smaller.

Viewing distance and picture quality: two parts of the screen size equation
Old-school tube TVs typically had screens 36" or less, and you didn't want to sit too close because if you did you'd notice the screen's scan lines. But with current TV models, sitting too far away may mean you miss some of the high-def detail you paid for.
But you also want to avoid sitting too close to your TV. You're too close if you find yourself distracted by the screen's "structure" — those rows and columns of pixels that look like tiny dots.
If you're not sure which screen size is best for your room size and viewing distance, use our charts as a guideline. It might also tip you off to how your current viewing distance lines up with industry recommendations.
You'll notice that we provided a range for each screen size, rather than a hard and fast number. That's because the viewing distance you prefer will depend on your personal tastes, as well as what kind of material you'll most often watch.
If you watch lots of high-quality video — like Blu-rays, over-the-air programming, or 4K streams — you can sit at the closer end of the range.
On the other hand, if you'll still be watching lots of lower-quality sources, we recommend sitting at the higher end so that you'll notice less of the image's flaws.
4K Ultra High Definition TVs have much higher resolution screens, with the ability to show four times the detail of a 1080p screen. The pixels on Ultra HD screens are incredibly small — even standing right next to the screen it's hard to discern individual pixels. This means you can sit much closer to an Ultra HD TV than to a regular HDTV — as close as 1 times the screen diagonal.
A few more tips on TV placement
Viewing angle is another factor that affects TV picture quality. No matter what display technology your TV uses — LCD, plasma, OLED — it will look its best when viewed straight-on, at eye level. With that in mind, you'll probably need a TV stand to support your TV and raise it to the correct viewing height.
Today's skinny, lightweight flat-panel TVs give you options: you can either go with a stand, or use a TV wall mount for on-wall placement. Wall-mounting saves considerable floor space and gives your home theater a nice, finished look. See our guide to wall-mounting your flat-panel TV for more detailed on-wall TV placement tips.
Choose a stand or wall mount that's made to accommodate your TV's weight and size. An old coffee table may not be able to stand up to the weight of really big TVs.
Also, be sure that your TV is placed properly on your stand, and that it's balanced left to right, and front to back. If you have small children, wall-mounting your TV is a good way to reduce the chances of an injury caused by a TV tipping over. Or, if you're placing your TV on a stand or other furniture, a TV safety strap is a smart safety option.
Rather than the traditional pedestal stand, many new TVs are supported by two legs placed out near the edges of the screen. You'll want to be careful not to place your TV so that the legs are close enough to slip off if the TV is bumped.
Since TVs tend to be heavier towards the front, you should avoid setting them too close to the front edge of the stand.

Room lighting and your TV's picture
Light from lamps and windows can also affect your TV's picture.
Properly done, it can have a positive effect, helping to prevent eye strain and providing deeper-looking blacks. But in a lot of cases, it can have a negative impact, creating on-screen glare and making your TV's colors look faded and washed out.
If your viewing room has a lot of ambient light from lamps and windows, there are some simple steps you can take to prevent it from negatively affecting your TV's picture.
Controlling your room's ambient light with window treatments and lamp dimmers can help your picture look its best at any time of day.
- If you can, take room lighting into consideration when choosing a spot for your TV. A little furniture shuffling might be worth it if it means your TV won't be directly across from West-facing French doors that create afternoon glare.
- Windows that let in bright sunlight should have blinds, shades, or curtains to keep reflections off the screen.
- Light from a window behind the TV makes it difficult for your eyes to adjust to the very different brightness of the TV screen. For watching during daylight hours, consider treating these windows with curtains and blinds.
- If you're concerned about glare in your room, consider an LCD TV — their bright, anti-reflective screens generally hold up the best in well-lit rooms.
- With just about any TV (except a projector), it's best to have a little bit of light shining on the wall behind it. If you watch in total darkness, the TV's range of brightness can cause eyestrain.
- Use dimmers in your home theater room to precisely control the amount of background light for optimum viewing comfort. For the greatest convenience (and the biggest "wow" factor), look for dimmers that are remote-controllable.
